Ammeter
The gauge marked "Amperes" indicates the rate of charge or
discharge of the battery It does not indicate the total output
of the generator at any time nor does it indicate the current
drawn by the starting motor when starting the car.
The ammeter should indicate on the charge side most of the
time; otherwise more current will be drawn from the battery than
is put into it and the battery will eventually become fully discharged.
Normally, when no lights are in use, the ammeter

especially in summer weather, it may indicate "Hot." This
is to be expected and will not interfere with efficient operation
of the engine. If it indicates "Hot" after short runs and

cause should be investigated.

the beginning of warm weather in the spring and left open until
the beginning of cold weather in the fall. Even in the closed position,
the ports are open slightly to insure efficient engine cooling.

should show "charge" as soon as the car is running ten or twelve
miles an hour in high gear. If it fails to show a charge under
these conditions, or if it shows a discharge when the engine is
not running and no electrical equipment is in use, the cause should
be investigated.
Temperature Indicator
The temperature of the cooling liquid is indicated by the
gauge marked "Temperature." For ordinary driving, after the
engine has warmed up, the indicator should stay within the

Throttle Control
The throttle of the carburetor (or of the two simultaneously
operated carburetors on the V-12) is controlled by a hand lever
and a foot pedal or accelerator. The normal position of the hand
lever for driving the car is all the way up to "CLOSED." In this
position the throttle of the carburetor is open just enough to
permit the engine to run at idling speed after it is warm.
The hand throttle should be opened only when the engine is to
be run at a speed slightly faster than idling, as when warming up
the engine. For starting a cold engine, the hand throttle should
alwavs be in the fully closed position to insure the proper pro-
